The aim of research is to develop a methodology for assessing the properties and behavioral characteristics of toxic pollutants, that will allow to examine the nature of the change of stability, controlling it. We systematized property parameters and energy parameters of pollutants, investigated characteristics of their behavior in the conditions of urboecosystem. We proposed a method that allows to assess the behavior of the aerosol stability, controlling the behavior of toxic pollutants in order to reduce their stability and, ultimately, to reduce air pollution.
